Influence of zinc coating to a temperature of steel members in fire

Jiří Jirků, František Wald


This paper describes effect of hot dip galvanizing of steel structure surfaces to temperature of steel members during the fire. Temperature in a set of specimens was measured during the second fire test at experimental building in Veseli nad Luznici. Experiment results show, that the zinc coating can reduce temperature in steel members especially in first fifteen minutes of the fire. The paper describes the process of experiment and analytical evaluation.
